codecrafters-shell-java

This is a starting point for Java solutions to the "Build Your Own Shell" Challenge.

In this challenge, I built my own POSIX compliant shell that's capable of interpreting shell commands, running external programs and builtin commands like cd, pwd, echo and more. Along the way, I learned about shell command parsing, REPLs, builtin commands, and more.

Note: Head over to codecrafters.io to try the challenge.

Start

Requires Java 21 and Maven.

You can run the shell using:

./your_program.sh

# Inside shell
$ echo Hello World from my own shell!
